After some Yoga Teacher Training courses, the title Yoga Acharya, which means “master of yoga,” may be given to a yogi. This is the case in the Sivananda tradition. After students graduate from the Advanced Yoga Teacher Training, the title is bestowed upon them.
In Hinduism, acharya is given as the formal title for a guru. There are five main traditional acharyas: Adi Sankaracharya, Ramanujacharya, Madhvacharya, Nimbarkacharya and Vallabhacharya. There are also modern acharyas, such as Sri Ramakrishna.
In Buddhism, an acharya is a senior teacher, such as Pema Chodron at Gampo Abbey.
